The simulation of an experiment of biology can be carried out on the screen of a computer. With the program, we can experience evolution like a roll playing game or we can experiment how genes are working. If the door of seven rooms are opened, the unique story of a euglena, paramecium, planarian, butterfly, bird, dinosaur and human can be seen. At the end of the story, researchers give us comments for us on each subject.

In the room of planarian,while looking at the screen, cut the body of planarian and watch its regeneration.In the room of paramecium,aggregation or conjugation of paramecium can be seen.
